MEANS FOR SECURING TIRE RIMS TO VEHICLE WHEELS.

Application filed February 2'7, 1920. Serial No. 361,905.

To all whom a may concern.

Be it known that 1. JAMES M. MUNDY, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Means for Securing Tire Rims to Vehicle lVheels, of which the following is a specification.

My invention relates to vehicle wheels of the type in which a demountable rim is used for the support of the tire in a manner well known in the art, especially as related to automobiles, the object being the provision of simple but effective means whereby the rim may be quickly and conveniently released or secured in position on the felloe of the wheel,--the invention consisting in the specific construction and arrangement of parts described and claimed, and distinctive features thereof consisting in the use of an annular clamping plate positioned on the side of the felloe for securing the tire rim to the felloe of the wheel,said clamping plate being formed for contactual wedgeplane engagement with a plurality of attachment lugs protuberant from the side of the felloe; and also in the use, in conjunction therewith. of corrugated locking means, all as hereinafter fully set forth.

In the accompanying drawings,

Fig. 1, is a front side elevation of a wheel embodying the essential features of my invention, the parts being shown in locked relationship;

Fig. 2, is a view like unto Fig. 1, the lock and bolt having been removed, and the annular clamping plate retracted and in position for removal from the felloe of the wheel; I

Figs. 18 and 19, are sectional'details, like unto Fig. 14, showing my annular clamping plate as used in connection with difierent forms of demountable tire rims.

The main, central portion of the wheel may be of any desired or known construction, that shown in Figs. 1, 2 and 10, consisting of the hub H, spokes S,.S, and felloe F, of an automobile wheel of well known parts. R, is the demountable rim of the clincher type, for the reception and support of the basic flanges of the shoe or tread of a pneumatic or other rubber tirein a manner so well known in the art that the representation of the tire .is omitted in the drawings. W, is a wedge ring, of ordinary construction, used to tighten and'hold the rim R, in position upon theperiphery of the felloe F, as shown more particularly in Figs. 3' and 14.

In some forms of detachable tire rims this wedge ring W, is dispensed with as .a

separate part, the rim itself being formed with a wedge portion 1", as in Fig. 18, against v ,1 plane contactual engagement therebetween,

Cir

1,44 ees as a means of detachably securing tne tire rim to the wheel felloe subst ntially herein set forth.

The annular clamping plate C, its the front side of tlw felloe, i i base or Wide side of the wedge rin when used, the t of the wedge 3? ing inserted between the periphery of the able riin in aforesaid Figs. 3 and i l. The clamping plate C, is supported upon the fellee by a plurality of What may be conveniently designated as a'a' tachinent lugs a protuberant from the side of the felloe and each formed with a shoulder 05' adapted to ove lap the outer face of sale. clamping pl C, which latter 's formed with elon concentric slots 0, c, for the accommodation of said attachment lugs a, an. in the drawings the wheel is shown as formed with four of these attachment lugs a, a al hough I do not liniit myself in this respect, since three five, or any desired number may bprcvided, according tn preference quireinents.

The contactual'surfaces 0?, of the shoul ders a, of the attachment lugs a, a, and the corresponding contactuai surfaces 0, of the annular clamping plate C, may both be correspondingly inclined with. relation to each oth r, as shown in Fig. 5, so as teattain mutually a. close, Wedge-like engage ment,or either one or the other of the interlocking contactual surfa es nained ((4 0) may be inclined to function Wedges, as illustrated in Figs. i5 and 16-the essen tial feaure in this respect being incli? ed Wedgeable contactual engagenieit between the annular clamping plate C and the attachment lugs a, a, which will insure the pressing of said clamping plate C tigl against the outer side face of the felloe F, when the plate C, is forcefully turned in the direction of the arrows Figs. 1 and 10, thereby driving th Wedge ring in betw en the fello F, and the tire rim D it a: 1n Figs. 3 1- or pressing against the rnn R, as in Figs. 17 and 18, and securing the latter firmly in operative position on the Wheel. Tins in F 15 the inclined surface (4 on the attachment lug a performs the function of a Wedge when the opposed ed e c of the slot 0, is driven against it While, conversely, in Fig. 16, the inclined surface 0, of the clamping; plate G, acts Wedge when driven against the end a", of the Shoulder a, of the attachinei-i lug a,-the result being the same in all three constructions shown in Figs. 5, 15 and 16, respectively, in that the plural Wedging operation involved in the forceful turning of the annular clamping; plate C, inthe direction of the arrows Figs. 1 and 10, insures the driving home'of the Wedge ring; W to its prescribed position between the dernountor reable riin as herenibe in l4 and Lo, t e case in 'l" e opera et forth the lulu C formed on 0U; 1110, e

departing from the spirit and intent of my invention in this respect. Furthermore,

while my annular clamping plate C, is preferably formed in one continuous piece, it also might be formed in sections, if preferred under certain conditions of use, so that I do not limit myself to the identical form of parts shown.

ll hen formed in a single )iece my an nular clamping plate C, thus constructed and arra ed in conjunction with the attachment lugs a, a, affords many practical advantages over he prior state of the art. Thus, by the removal of a single bolt 7), and the forceful tapping of one or more of the thrust shoulders c, the clamping plate C, be quickly and conveniently loosened up for removal to admit of the substitution of anew rim and tire, and as quickly re iced and firmly secured in position,the e bolt 7), being the only removable and cplaceable securing means other than the ular clamping plate itsel f, and the latter, by its wedge-plane contactual engagement with the plurality of attachment lugs a, a. enables me to dispense with the plurality of bolts heretofore requisite to secure the tire rim to the felloe of the wheel. Hence the time and labor involved in replacement of tires is lessened by my invention as compared with the methods and means heretofore in vogue where a plurality of screw bolts has been deemed essential for the purpose.

n in

rom the foregoing it will be seen that a inctiye and essential feature of my inis the annular clamping plate C, fitted to the face side of the felloe and formed with a plurality of elongated. concentric slots 0, in conjunction with the attachment lugs as, protuberant from the side face of the felloe.the contactual ci'agagement between said attachment lugs a, and the said coupling plate C, being wedgeable,

r the purpose set forth. An auxilture is the locking means provided positively securing the wedged co-relati :1 of annular side clamping plate and felloe by the use of a single bolt, the loosenof which admits of the uncoupling of the wedge-engaged parts by a slight partial rotation of the clamping plate C, which may be instantly effected by a hammer tap applied to one of the thrust shoulders c, or by equivalent means, after the loosening of a single bolt. 7

This function of practically instantaneous release is of import in any emergency, but especially so in connection with fire apparatus, and other emergency Vehicles, where delay in the substitution of wheel. tire might result disastrously.

What 1 claim as my invention and desire to secure by Letters Patent is,

1. In combination with a wheel of the character designated, a demountable tire rim, rim wedge means positioned between said tire rim and the periphery of the felloe, an annular clamping plate fitted to the side of the felloe and formed with a transversely corrugated. portion and also with a plurality of elongated concentric slots, shouldered attachment lugs protuberant from the side of the felloe, and fitting the said elongated concentric slots in the annular clamping side plate, the contactual surface engagement between said shouldered attachment lugs and the outer face of said annular clamping side plate being wedgeable, a transversely corrugated locking plate engageable with the aforesaid corrugated-portion of the annular clamping plate, and means extended into the felloe, through the annular clamping side plate, and through the locking plate for positively securing said locking plate in position, for the purpose described.

2. In combination with a wheel of the character designated, a. demountable tire rim, rim wedge means positioned between said tire rim and the periphery of the felloe, a split annular clamping plate fitted to the side of the felloe the end portions of which plate are formed with transverse corrugations, said split annular clamping side plate being also formed with aplurality of elongated concent ic slots, shouldered attachment lugs protuberant from the side of the felloe and fitting the said elongated concentric slots in the annular clamping side plate, the contactual' surface engagement between said shouldered attachment lugs and the outer face of the said annular clamping side plate being wedgeable, a transversely. corrugated locking plate cngageable with the aforesaid corrugated end portions of the split annular clamping side plate, and a securing bolt extending into the felloe, through the annular clamping side plate, and through the said locking plate, for the purpose described.
